Sounds like you're having a bad day. You just need to learn from it, put it behind you, and try again.
I have been flying commercial jets for years, yet not so long ago, I cut in too tight on a visual, got too high and had to go round. Embarassing, yes, dangerous, no. Put it behind me and get it right the next time.
Remember, Aviate, navigate, communicate
And the two golden rules:-
1. Always fly the plane
2. Don't forget Rule 1
Incidentally, sounds like you have your head in the cockpit too much. When my students used to do that I'd cover the main instruments with Posted Notes and make them look out the window. They were usually amazed as to how accurate they could be !! Try it sometime with your instructor.
